MACHINE FOR FORMING THE JOINTS BETWEEN THE.HEADS AND BODIES 0F CANS.

SPECIFICATION forming part of Letters Patent No. 269,908, dated January2, 1883.

. Application filed November 3, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, ROBERT C. ANDERSON, of Bayonne, in the countyotHudson and State of New Jersey, have invented a certain new and usefulImprovement in Machines forForming the Joints between theHeads andBodies of (Jans, of which the following is a specification.

Thisimprovement relates to machines which are employed to squeezetogether the overlapping parts ofthejoiuts between the bodies and headsof sheet-metal cans; and the object. of the improvementis to facilitatethe adjustment ofthese parts into the proper position to be acted on bythe squeezer-jaws.

Theimprovementconsistsinthecombination, with a rest for a can-head andsqueezing-jaws for acting upon the can-head while on the rest, of guideshinged in place at the outer end and adapted to close around thecan-head after it is placed on the rest, so as to insure its occupyingthe proper position, and to serve as guides for conducting the body intoplace.

The improvement also consists in the combination, with a rest for acan-head and squeezthe rest of guides hinged in place at the outer endand connected to a lever, whereby they may be lowered after the can-headis placed on the rest to center it thereon and to form guides forconducting the can-body to it.

The improvement also consists in the combination, with a rest for acan-head and squeezing-jaws for acting upon the can-head while on therest, ofguides hinged in place at the outer end and connected to alever, whereby placed on the rest' to center it thereon and guide thecan-body to it, and intermediate guides which are lowered by overhanginglips on the guides first named, and springs acting on these intermediateguides and serving to raise all the guides.

In the accompanying drawings, Figure 1 is apartially-sectional side viewof a machine embodying my improvement. Fig.2'is aplan or top view of thesame. Fig. 3 is a sectional view of its upper part.

Similar letters of reference designate corresponding parts inall thefigures.

A designates the frame of the machine. It may be made of any suitablematrial and construction.

B designates a rest, provided with a rim or shoulder, a.

G designates squeezing -jaws, which are adapted to have a sliding motiontoward and from the rest, and to squeeze the-overlapping parts of thejoint between a head and body of a can between them and the rim orshoulder a of the rest B. Levers D, fulcrumed between their ends to theframe A, project at the upper ends through slots or holes bin thesqueezing-jaws C, so as to impart motion to them. At the lower-ends theyare connected bylinks E to.a head, F. This head F is connected by rod,G, to a lever, H, which at the rear end is fulcrumed to the frame A, andat the forward end is connected by a link, which is connected to a crankor eccentric, W, arranged upon a shaft, V, that may be driven by steamor other power.

U designates a presser pivoted to the forward end of a lever, X, whichisfulcrumed between the ends to a stand, d, erected on the the frame A ofthe machine, and at the rear end is connected by a rod, '1, to a lever,S. This lever S extends to the front of the machine, where it may beoperated by the foot of the attendant. A spring, 1, connecting thisleverS to the frame A, raises it when it is not operated by theattendant, and thereby effccts the raising of the presser U. When thelever S is depressed by the attendant the presserU will descend upon thetop of acanbody fitted to a can-head upon the rest B.

J J are guides, which preferably will be made of metal, and are hingedat the outer ends to the frame A of the machine so that their inner endsmay be brought down around the rim or shoulder a of the rest B or may beraised away'therefrom. 'lheir inner ends conform to the exterior of therim or shoulder a of the rest, and when they are brought down they fitclose to the same. The guides J areconuected by rods K to levers M on ashaft, L.

One of these levers M is connected by a rod,

0, to a lever, P, which is fulcrumed to the frame A, and extends to therear or back of the machine. The intermediate guides J are ICC alsohinged at the outer end to the frame. Lips e upon the guides J overlapthe guides J, and hence when the guides J are depressed the guides J arealso depressed. Springs Q, arranged between the frame A and the guidesJ, tend to raise these guides, and by raising these guides they causethem to act upon the lips c, and raise the guides J also.

A can-head is thrown or carelessly placed upon the rest 13, and a boystationed at the rear of the machine depresses the lever I, whereuponthe guidesJ J descend and center thecan-liead. The ends of these guidesare bent downward at an angle, so that when depressed they will togetherform a funnel-like trough. A can-body is thrown or carelessly placedwithin the guides, and is by them conducted into proper position uponthe can-head. The attendant at; the front of the machine now depressesthelever S, thereby causing the presser to descend upon the can-body.The squeezingjaws then move up against the canhead and squeeze theoverlapping parts of the can-head and canbody together. The guides J Jlessen the amount of care required to place the can-head and can-body inposition, and therefore reduce the labor and expense of making thejointsof the cans.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination, with a rest for a canhead and squeezing-jaws foracting upon the can-head. while on the rest, of guides hinged in placeat the outer end and adapted to close around the can-head after it isplaced on the rest, so as to insure its occupying the proper positionand to serve as guides for conducting the body into place, substantiallyas specified.

2. The combination, with the rest for a canhead and squeezing-jaws foracting upon the can-head while on the rest, of guides hinged in place atthe outer end and connected to a lever, whereby they may be loweredafter the can-head is placed on the.rest, to center it thereon and toform guides for conducting the can-body to it, substantially asspecified.

3. The combination, with a rest fora canhead and squeezing-jaws foracting upon the canhead while on the rest, of guides hinged in place atthe outer end and connected to a lever, whereby they may be loweredafter the can-head is placed on the rest, to center it thereon and guidethe can-body to it, and intermediate guides which are lowered by overhanging lips on the guides first named, and springs acting on theseintermediate guides and serving to raise all the guides, substantiallyas specified.
